滑坡勘查中的放射性测量方法和异常释

Radiometric Method and Abnormal Explanation of Landslide Survey

研讨了滑坡放射性勘查机理,介绍了应用放射性测量技术及其异常解释模式。在重庆市万州区233古滑坡和云阳新县城寨坝滑坡上,滑坡体地质形态(边界及滑体厚度)的试验验证结果表明,它可用于确定滑坡体边界(缘)线;研讨滑坡体中地下水流方向及滑坡体运动方向;解释计算预测滑坡体强风化带深度(滑体厚度)。同时,与地质和钻探配合,还能提高滑坡勘查的地质效果。

Radioactivity exploration mechanism of landslide is researched. Radioactive measure technical and its anomaly explaination models of application is introduced. Test verification result of landslide body geological form (boundary and landslide body thickness) in the district of Wanzhou 233 of Chongqing city ancients landslide and the Yunyang new county Zhaiba landslide shows, it can be used in determining the body boundary (reason) line, investigating the underground current direction and landslide body moving direction, explaining that calculation of weathered zone thickness of landslide body. It can also increase the geological effect of landslide exploration in adaption with geology and drilling.
